One mole of an ideal gas requires 207 J ...

One mole of an ideal gas requires 207 J heat to raise the temperature by 10K When heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by 5K, then the heat required is

A

62 J

B

124 J

C

12.4 J

D

6.2 J

Text Solution

Verified by Experts

The correct Answer is:
1
`207=C_(p)xx10`
`DeltaQ=C_(v)xx5`
`C_(v)=C_(p)-R =12.4`
`DeltaQ=nQ DeltaT=62 J`
`C_(p)=207`
`C_(v)=20.7-8.3=12.4`
`DeltaQ=1xx12.4 xx5`
